BRICK AND TILE MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,698, dated October23, 1888.

Application filed February 16, 1888. Serial No. 264,293. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK E. FREY, a citizen of the United States ofAmerica, residing at Bucyrus, in the county of Orawford, in the State ofOhio, have inventeda new and useful Improvement in Brick and TileMachines, of which the following is a specification.

My invention has relation to improvements in automatic cut-offs forbrick and tile machines; and the object is to provide a cut-off to severthe slab or column of clay into lengths on the carrying-belt of thetile-table, which cut-off is operated by the carrying belt, impelled bythe movement of the unsevered part of the slab of clay as it progressesfrom the ma chine.

The novelty of the invention audits nature are specially pointed out inthe claims made hereto.

I attain the purposes of my invention by means of the mechanismillustrated in the accompanying drawings, wherein Figure l is aperspective of my improvements attached to a brick-machine. Fig. 2 is aperspective of a section of the endless belt, showing the angle-irons orarms which operate the cut-off. Fig. 3 is a detail view of a pair of theangleirons removed from the belt. Fig. 4 is a perspective of the reelwith the cutoff wire. Fig. 5 is a plan view of the tables. Fig. 6 is amodified form of the table and cutoff. Fig. 7 is a detail view of thesupportingbracket for the cut-off.

The same parts appearing in the different figures of the drawings aredesignated by the same notations, and reference being had there to, Adesignates the frame of the tile-table. which consists of parallel sidepieces, 1, united by suitable cross-ties and supported on legs, as at 2.The side pieces are arranged at such distance apart as to take betweenthem the endless carrying-belt B, which is arranged on rolls or drums 34 at each end, the former of which is of larger diameter than the latterto give greater frictional surface in its contact with the endless belt;but both drums are arranged to carry the upper line of the endless belton a horizontal line and a little flush of the upper surface of the sidepieces of the frame. A

series of rollers, 5, as indicated in Fig. 6 of the drawings, isjournaled in the side pieces and sustain the endless belt in ahorizontal position and from sagging below its proper line of movement.Secured to and arranged across the endless belt B are a number of metalrods, 6, or cross-bars, the ends of which project be youd the edges ofthe endless beltand over the sides of the frame and are formedwithjournals 7 on the projecting ends, andsecured and fitted onthejournals at each side of the endless belt are angular irons 8,consisting of two arms arranged at right angles, which are pivoted ontheir hearings in the intersecting angle of the arms, the angle on theoutside being rounded to prevent them from catching as they are movedover the ends of the belt-supporting rollers in the frame. These irons 8are the means by which the reel of the cut-off is rotated and made toperform its duty of cutting off the forms. They are placed at determineddistances on the belt in order that the slab may be severed in thedesired lengths. On the carrier-belt between the cross-bars 6 aresecured pads of felt, 9, or any other suitable yielding material, uponwhich the continuous slabs of clay are pushed and are carried along onthe apron upon them. These pads serve the following purposes: First,they keep the clay from contact with the crossbars on the apron, thuspreventing the under side from being damaged; second, they afford ayielding bed for the outting-wires to impress themselves slightly belowthe under surface of the column of clay. It will be observed that whenthe wire is traversing the space where the cutting-arm of the reel isvertical it moves somewhat faster than in the other regions of thecutting arc, owing to the peculiar engagement of the arm of the reelwith the vertical arm of the angular iron. To carry the forms out of theway of the Wire, a secondary table is provided, hereinafter described,the apron of which moves faster than the apron of the main table, sothat when the form is severed it is in contact with the apron of thesecondary table and is drawn out of the way of the wire in its ascendingmovement.

Secured on each side of the table-frame is a bracket, 10, in which areadjustably arranged the stems .of bearing-boxes 11, in which are mountedthe journals of the shaft 12. On the reel is secured a small roller, 15,which engages with the angular irons 8, and as these irons move forwardthe rollers are run down the length of the iron, causing the roll torotate, and of course carry the wire through the clay. The horizontalarm of the iron serves as a base-piece to keep the vertical arm of theiron from yielding backward. The small rollers serve to keep themovements synehronistic. As itwillbe perceived,in order to obtain asquare cut, the clay, the endless belt, with the angular irons and thereel, must all be moved in unison, a condition which permits the wire ona revolving cutter to cut square through the longitudinally moving bodybeneath it. It will be perceived that this is accomplished simply bymaking the slab serve as the power to revolve the cutoff. It isessential that the cutting-wires be arranged on a line with the axes ofthe rollers on the reel-arms; otherwise the cut will be curved. Itherefore attach to the inner faces of the reel-arms smallspring-supports 23,with open end slots, 24:, in which the cutting-wiresare seated. In the supports 23 are set'screws 25, by which the tensionof the wires is adjusted.

G designates the second or auxiliary table, which consists of siderails, 16, connected together by cross-pieces and mounted on supports ofany suitable kind, substantially as shown. In each end of this frame isjournaled a roller, l7 18, about which is stretched an endless apron,19, to receive and carry the forms from the main table. The shaft of oneof the rollers is extended and has fixed thereon a band-pulley, 20, onwhich is arranged a belt, 2I,which is extended and arranged about alarger pulley, 22, on the shaft of the drum of the main carrying-belt.It will be per ceived that the endless apron of the secondary table isdriven by the motion of the endless apron of the main table andprimarily by the movement of the clay from the machine, and also thatthe power is so arranged as to drive the apron of this secondary tablefaster than the apron of the main table.

To prevent distortion or breakage of the forms in their passage from onetable to the other, I arrange a small roller, 26, between the adjacentends of the two tables to carry the forms. I prefer to support thisroller on bearings 27 on the side pieces of the main table and give itrotary motion by small belts 28, extended to and arranged about the endroller of the secondary table.

In Fig. 6 of the drawings I have shown a modified arrangement andconstruction of the angular arms and reel in connection with the slab ofclay and apron of the main table. In this construction I arrange ashaft, 29, under the main table and on the end fix a sprocketwheel, 30.The end of the shaft of the roller or drum 3 is extended, and asprocketwheel, 31, is fixed on the extension, as shown, and about thesesprocket-wheels is arranged an endless belt, 32, on which atpredetermined distances are pivotally secured the angular irons 8. Ialso extend the shaft 12 of the cutofif and mount thereon a spider ofthe sameconstruction of the spiders of the reel, as hereinbeforedescribed. The operation and result are identical with that attained bythe construction herein first specified.

In the passage of the euttingwires through the clay it happens that claywill adhere to them. In order that they may be cleaned, I arrange abrush to contact with them and brush off the adhering clay. The deviceconsists of a frame, 33, the legs of which are adjustably supported inthe bracket 10, substantially as shown, and on the horizontal bar of theframe is secured a brush, 34. To catch the sweepings from the wires, Isuspend a trough, 35, on the shaft of the reel, as shown.

What I claim is 1. The combination, with a brick-machine, of atile-table provided with an endless apron adapted to be moved by theprogression of the column of clay, angular irons pivotally secured tosaid apron at predetermined distances, a cut-off reel mounted over theend less aprons, and rollers on the ends of the arms of the reel toengage with the vertical arms of the said angular irons, substantiallyas described, and for the purpose stated.

2. In a tile-table of the kind herein described, an endlesscarryingapron having a continuous inner surface and a covering of feltdivided into sections, substantially as described.

3. In a tile-table, the combination, with the endless carrying-apron, ofangular irons, as 8, pivotally mounted on cross-bars secured on theapron, pads of a yielding material secured on the endless apron betweenthe said crossbars, and a cut-ofi' mounted over theendless apron andadapted to be operated by the vertical arms of the angular irons,substantially as described.

4. The combination, in a tile-table, of an endless apron, angular irons8, pivotally secured on the said apron, a cut-off reel mounted over theendless apron. rollers on the ends of the arms of the reel to engage thevertical arms of the angular irons, a secondary tile-table at the end ofthe main table provided with an endless carrying-apron, and means,substantially as described, for moving the endless apron of thesecondary table, as specified.

In witness whereof I have hereunto set my hand in the presence of twoattesting witnesses.
